The TMP36 is a low voltage, precision centigrade temperature sensors. It provides a voltage output that is linearly proportional to the Celsius (centigrade) temperature. The TMP36 does not require any external calibration to provide typical accuracies of ±1°C at +25°C and ±2°C over the -40°C to +125°C temperature range. The low output impedance of the device and its linear output and precise calibration simplify interfacing to temperature control circuitry and ADCs.
